Serial No. 234,356.

To all Hf/LOH! it may concern Be itknown that I, HENRY F. Nuwnunr, a citizen of the Unlted States, residing in the borough of Brooklyn, city of New York,

county of Kings, and State of New York, 5

have invented certain ne and useful Improvements in Signal Apparatus, of which I the following is a full, clear, and exact do scription, reference being had to the drawings accompanying and forming a part of the same.

This invention relates generally to signal apparatus in which a person at a given pointer station can cause a portion, normally in an inoperable condition. to more or he put into an operable condition and a signal to be given by the movement of a car or similar moving object as it approaches a given point and to restore the parts to their normal condition.

. Inthe embodiments of my invention shown in the drawings, Figure 1 illustrates diagrammatically the circuits, their terminals, means for closing and opening such circuits and also the general construction of? the system or apparatus by which the signals are given both in a car and at local stations j to be served by such car, there being signal devices for giving such signals to two cars and the stations served thereby thus shown; Fig. 2 is a front view showing the switch devices, the means by which the movable parts are moved to bring the circuits from an inoperable to ap operable condition, means by which such circuits are held or retained in operable condition and means by which such circuits are restored to an inoperable condition; Fig. 3 shows in longitudinal section on line 33, of Fig. 2, that which is shown adja went to that line in this Fig. 2; Fig. t. shows in cross section on an enlarged scale,

In Figs. 1 to 9 inclusive there is shown one embodiment of my invention. As here 19 and 20 show in front elevation details of terial passes over shown the signal circuits are rendered normally inoperable by bodily moving that portion of each circuit connected to the switch device into a position where it is inoperable by the means provided for operating such devices in giving the signals. As thus shown each switch device is provided with one portion, member or part which is bodily'movable into and out of operable condition for giving signals, which meur her or portion has a part which is made yielding relatively to its point of attachment to the part by which it is carried and bodily moved, and, hence, the movement of such portion or member is not seriously interfered with when brought into engagement with the means it coacts with in closing the circuit or circuits. Also as thus shown there are two of these yielding parts for each of such portions or members thus mounted on a single support and they are insulated from each other and are adapted to operate two diiferent signals, for instance, a signal in the car and a signal for one of the stations or floors of the building. Each of these movable members of the switch devices, when the devices and their respective circuits are brought into operable condition, contacts with a piece of conducting material mounted on a carriage which moves at a given or regulated rate of speed, as the elevator car or similar object moves, in Front of and over such members at substantially right angles to the direction in which such members of the switch devices are mounted to move. The contact between such conducting mate rial and movable members of the switch devices a yielding one and it is also a. rubbing or scraping contact, Each insulated partot the movable members or portions of the switch devices is connected to one pole of a source oi energy and the conducting material, mounted to move with the carriage, is connected with the other pole. From this it results that when the movable members of the switch devices are moved into their normal positions there is an air space between the conducting material mounted on the carriage, and each of the movable members of the switch devices, as such mathem, sufiicient to prevent the passage of current from one to the other and, hence, the switch devices and their respective circuits are in an inoperable condition. lVhen the switch device or devices are moved toward the path of movement of the conducting material mounted on the carriage so that contact is' made, between such member or members and the conducting material, current passes from one to the other and the signal or signals are operated and the switch devices and also the circuits connected therewith are in operable condition. That is, both the circuit and switch device are in condition to be operable by the passage of the conducting material over them, as the car or other object moves relatively thereto. Also as here shown automatic switches, operable by the movements of the mechanism by which the car or similar object is moved, or otherwise if desired, are employed to successively open and close portions of the circuit, so that as the car or similar moving object moves in one direction the circuit or circuits are broken for sub stantially one half of the signals and those for the other half are closed and the signals a-re'operable by the signal operating switch devices shown, whenever the movable portions or parts thereof are moved, so as to put their circuits in operable condition for contact with the conducting material on the carriage, as it moves over the same. These automatic switches hold one portion of the circuit or circuits in the-closed condition at substantially all times, for instance, as the car moves up the circuits for the up signals are closed at that-switch and those for the down signals are open at that point or points, and vice versa, therefore, the desired circuits, accordingly as the car moves, arepractically always closed by these automatic switches and, so far as such opening and closing of the circuits is concerned, they are normally in operable condition. Automatic switches of this general character or class are well known.

In Figs. 2 to 8 one construction and arrangement of parts is shown which are to have supplied, if desired, the circuits, sig nal devices and connections diagrammatically illustrated in Fig. 1 and operable as hereinafter described, and two (a plurality) cars are to be served, that is, signals are to be given to either of two cars. A, A, A, &c., designate in these figures the switch devices connected with the signal circuits for giving signals to each of the up moving cars, there being, as here shown, two of such circuits connected with each switch device, one for the signal in the car and one for the signal at one of the stations or floors of the building. These signal circuits, (which include their respective switch devices,) are normally in an inoperable condition by reason of a portion of each circuit being normally out of the path of the movement of means which are provided for closing such circuits. As here shown a portion or portions of each of the switch devices are made movable relatively to such path of movement to bring the circuits into and out of operable condition. A A A, &c., designate the switch devices for giving the signals to each of the down moving cars. Each of these switch devices have two yielding parts for each of the movable poi-tions or members, both of which are movable together, to put the circuits connected with them into operable or inoperable condition.

Each of these parts, as here shown, form a. portion of their respective 'cir cuits. These parts for-the up signals of movi gears are designated as a, a a &c'., respectively, and for the down signals of movingcars, as a a a 620., respectively. Two of these parts or'terrn'inals, as a and-o or a and (f, are mo-unt e don a single block of insulating material, and, therefore, each is insulated from the other. Thus the parts or terminals a and a are mounted on insulating block m, terminals or members a and a on block m parts orterminals a and a on block'm and terminals or members a and a] on block m &c. Each of these blocks of insulating material is in turn mounted on a movably mounted part or controller, as, n, n ,-n &c., respectively, (as seen in Fig. 6,) which in turn is mounted to move in a fixed support, as 0, 0 0 620., respectively. These fixed supports are mounted in the frame F of the apparatus. One of these supports, as 0 of switch device A is seen in Fig. 6, and itis shown partly in section to better illustrate the relations of the parts. As here seen the block m is seen when looking upwardly from the lower portion of Fig. 2, and portions of the means by which the controlleror part a and block m are caused to move are shown, The block m and movable controller or part a are seen in Fig. 6 in their normal positions, that is, in the positions they occupy when the circuits and switch device are in an inoperable condition by reason of the circuit or circuits being broken at the parts or terminals a and a which are then out of contact position relatively to the portion of the appaatus with which they contact to operate'the signals. These terminals or members a and a the insulating block m and the part a), to which such block is attached, are seen in the contact position in Fig. 4, and also in Fig. 6*. These parts m and n are caused to move into the positions seen in Fig. (3 by' a spring Z and to move into the positions seen in Fig. 6 in full lines, by an elbow lever 9 engaging with a stud or projection p on part or controller 12. a link, as T and armature 8 as seen in, full lines at the right of Fig. 4. This armature s is actuated by electromagnet S which is in circuit with a push button or circuit closing device at one of the'floors of the building. so thatwhen such button is pushed, by a person desiring to signal the car, a circuit is closed and the electromagnet is energized and the parts m and n are moved from the position seen in Fig. 6, against the stress of spring Z, intov the position seen in full lines in Figs. 4, 9 and 6 where. they are held by aretaining device T shown in Figs. 7 and 8, where the parts m and a are in their normal positions (as shown 1I1 Fig. 6), and the switch devlce and circuits are in an inoperable con point.

d'ition. These yielding parts or terminals 0;, a 0 &c., blocks m, m m 620., controllers a, n M, &c., springs Z, Z Z &c., constitute movable members or portions of the. switch-devices, as A, A A &0. As herein shown these movable members or portions of the switch devices are arranged quite near one another and it may be said that they are arranged at or near a common WVhen these members, portions or parts are thus arranged each one, when in operable condition, may be actuated independently of each of the others by a device or carriage of comparatively small size which is movable in a given path ot movement as a car or other similar obj ct moves, as hereinafter explained.

It will be entirely obvious to any mechanic that where more than one elbow lever, as is connected withthe link, as 7*, as seen in Figs. 2 and 5, that a single spring will move the parts, as 11. from the position seen in Fig. 6 to that in Fig. 6. These retaining devices T, T T &c., are mounted to slide on studs or projections as u, M 14 &c., more clearly seen in Fig. 7 formed on the fixed supports as 0, 0 0 &c., and they are moved into holding or retaining position by suitable springs as o, e e &c., one

. spring being sufficient for one device, as T as indicated in Figs. Sand 7 These retaining devices, as thus arranged, are always movable into retaining or holding position. whenever the part or parts, as W are moved against the stress of the spring or springs, as Z and room is made for the portion or 1 portions as t, t, of device T to pass under the lower end or ends of parts as W, by the stress of spring or springs, as 11 Each of these retaining devices thus shown retain or hold corresponding switch devices, as A A in operable condition, until such retaining device is moved from the position seen in Fig. 9 to that seen in Fig. 7. As thus shown each device, as T is provided with two proj ections, as i 6 by which the device is movable out of retaining or holding position and the controllers of the movable portions or members, as W, may be released and the switch devices be restored to an inoperable condition. These retaining or holding devices, as T, T T &c., are actuated into the retaining or holding positions by a spring or springs, as o, '0 12 &c., and into releasing positions by means mounted on the carriage B and carriage B These carriages are, as shown, duplicates of each other, and they are mounted to move relatively to and past the switch nd retaining devices, one carriage for each elevator car, as X and X as indicated in Fig. 1. These cars X and X are caused tomove by any well known or desired means suitable for that purpose. These means are indicated in Fig. 1 by ropes Y and Y and wheels y and respectively, and may be adapted to move as the car or cars move at any desired rate of speed. Connected with each of these car operating means there is a suit. ble speed reducing mechanism of any desired or known form, which may reduce the speed to the desired extent for moving the carriages B and B one of'which, as carriage B, is shown as being moved in one direction bythe reducing mechanism R connected with car operating means y in any desired manner and cord, or rope m and the other carriage B? is shown as being moved by the speed reducing mechanism R and rope or cord m In practice it has been found that a reduction of speed by these reducing mechanisms of from twelve feet for the car to two' or one and one half inches for the carriage, or thereabout, is a convenient extent of reduction in speed to make a compact apparatus for' operating the signals for elevator cars, as the same are generally run at the present day.

The carriages B and B are mounted to move and be guided by suitably shaped rollers, as b, 5 b &c., Figs. 2 and 8, mounted on suitable standards, as L, L 'L &c., attached to the frame F in any desired 'n'ianner for this purpose, two of which standards may be made integral with one another or otherwise, as desi'red, as for instance, standards L L seen in Fig. 4:, on which the grooved rollers b and b are mounted. These rollers, as Z), b V, &c., and standards, as L, L U, &c., may be so arranged on the frame F that the carriages B and B will at all times be held in position to operate as described, each carriage being preferably held within the grasp or under the control of at least two pairs of such rollers when at the two extremes of its moveinent by its reducing mechanism. Preferably the carriage or carriages, with the parts ca"rried thereby. shall be of such a weight .that gravity will suit-ably move it or them iii one direction, the reducing mechanism controlling its speed of movement under the action of gravity, as well as when lifting such carriage against gravity. These carriages I Qe-caused to move back and forth rela- -tively to the switch and retaining devices in any desired manner, but the foregoing has been found a convenient manner in use. At 'ta'ched to each"carriage, but preferably in sulat edjtherefrom, are suitably shaped pieces of fcdndu' in; material 'C and C one for Leach carriage, with which one pole of the w {source of energy may be connected, if desired. These pieces of conducting material,

' .as C and C are preferably of such a shape that each moves past the switch devices with WlHClI it 18- to connect, and as shown, each one s formedof one piece of material having one portion suitably shaped to connect with the switch devices in operable condition to give signals when the car is moving upwardly and another portion to connect with the switchdevices in operable condition to give signals when the car is moving downwardly. Also as shown these pieces, as C and C are so shaped that the switch devices, connecting with the signals for the floors of the building contact with such pieces before they. do with the switch devices connecting with the signal inthe car. The signals are preferably given as the car or cars approach the station or floor from which the signal was sent and also some little distance away. If desired the signal at each floor may be operated when the car is substantially three floors away while the signal in the car may be operated when the car is substantially two floors away. These pieces, as C and C may be otherwise shaped as desired and they may be of any desired proportions to operate the signals and hold them operated for any desired distance,

these being matters which each individual constructor will arrange to suit his needs. As thus shown the switch devices are each i'estorable to their inoperable condition at given points in the movement of each cari-iage relatively to the floors of the building, and when thus restored the signals are extinguished or cease to act as such, until the switch device or devices are again brought into operable condition by the means employed forthis purpose. The point or points at which these switch devices and circuits are to be restored to an inoperable condition or-cease to operate is also a matter which will be determined by each individual constructor.

Each carriage, as shown, has'attache'd to it, two pivotally mounted parts, as 0 and 0 for carriage B, or c and c for carriage B, which cooperate with projections, as 2', 2 ,6, &c., on retaining devices T, T T .&c., to move such retaining or holding devices out of engagement with the movable parts of the switch devices, as n, n n &c.,-to release such parts and restore the switch'devices and their circuits to an inoperable condition.

The pivoted pieces,.as c, 0 c 0 &c., form restoring means which, as shown, act on the projections, as i, i, 2' &c., on retaining .devices, as T, T T &c., to move such devices out of retaining or holding positions and release the movable portions or members of the switch devices and restore the same and their circuits to an inoperable condition. Pivoted pieces, as c and 0 act on one portion of these retaining devices, as the carriages, asB and B respectively, move in one direction, and pieces, as 0 and 0 act on another portion of these retaining devices as such carriages move in the other direction. These pieces, as c, 0 0 and 0 are preferably pivoted to brackets, as c, 0, 0 and 0 F ig. 4, and are substantially free to move in one direction, but are held in actuating position andagainst movement in the other direction lows that if the pivoted piece, as 0 seen in Fig. 5, moves in the direction of the arrow adjacent thereto the pin or projectionas 0 will prevent such piece as 0 from being moved and it will beheld in actuating position, so that the inclined face at its end will engage with the projection, as 2' on retaining device, as T and actuate the same, moving it against thestress of its actuating spring, as if, until the movable parts or controllers, as at}, of switch devices, as A and A ,,have been released from the retaining or holding action of the projecting parts, as t and if, and permitting the stress of the spring or springs as Z and Z on controllers, as n m of switch devices, as A and A 'move such movable portions or members and restore the switch devices to an inoperable condition. If the retaining device, as T seen in Fig. 5 is in the position thereseen and the carriage ismoving so that pivoted piece, as 0 moves in a direction opposite to that indicated by the arrow, then, assumingthat the piece had been moved by the carriage. below projection, as 2' asit would have done in actuating the retaining device, as T in ordinary'practice, that edge of this piece, as 0?, which rests against pin or projection, as 0 wouldengage with projection, as 2' and, as;the carriage moved upwardly, such piece 0 would be moved out of actu- 'ating position against the stress oi spring, as 0 until piece, as 6?, could pass projection, as 2', without moving it or the retaining device, as 1. Then as the carriage moved on the spring, as o would restore thispivoted piece c vinto itsactuatingposition, that is, to'the positionthere seen, ready to actuate device T ,as the carriage moves in the return direction, or inthe directionindicated by the arrow, as'just before e plained. These pivoted pieces are thusiao' tive as the carriagemoves in one'direction upon one portion of the'retaining devices and inactive upon another portion {normatter in which direction the carriage moves, relatively to the switch and retaining jdeviees. These pivoted pieces also form means which .are activeto move some one or more of the retaining devices as the carriage moves in one direction and also are inactive to move the sameretaining devices when the carriage moves in the other direction. They also form portions of restoring means which i are adapted to move relativelyto the retaining devices in two directions and providemeans which are active on some and inactive on other of the retaining devices when moving in one direction and active on the devices when moving in the other direction, on which such means was before inactive. They also form means for restoring the switch devicesand circuits to an inoperable condition portions of which are separately mounted to move relatively to the retaining devices, that is, one portion as c'and a is mounted on carriage l3 and another portion,

asc antic", is mounted on carriage B and,

hence, each portion is mounted to move as its own individual carriage moves independently of the movement of any other carriage, the movement of one carriage not aii'ecting the movement of the other, as each moves in accordance with the movement of the car with which it is connected. These pivoted pieces, by reason of being mounted on the carriages, necessarily move in unison therewith, and, as theconducting pieces, as C and C are also'mounted on the carriages, such pivoted pieces also move in unison with the conducting pieces as they move relatively to the switch and retaining devices.

Each elevator car or similar object is provided with an automatic switch,,as shown in Fig, l, which is operable as the car changes its direction of movement. These automatic switches, as E, E are each provided with four contact points and a pivoted arm, so combined with the car operating means that asthe car moves in one direction this arm is in electrical connection with two of the four contact points and when the car reverses its direction of movement such, arm moves, breaking electrical connection with such two contact points and making electrical connection with the other contact points, this taking place with each reversal of the direction of movement of the car and carriage. These switches as E and F arepreferably arranged in connection with some revolving part oi the car operating means, so that some portion or the switch, as J, or. J is in frictional contact with such revolving part of the operating means and it has a limited extent-of movement as such revolving part reverses its direction of movement, which extent .is sufficient to move the pivoted arm, as e, of

switch, as E, or of arm, as e, of switch, as

E the distance requiredto connect and disconnect such arms with and fromthe pairs of contact points, as shown in Fig. 1. Switch, as E, is provided with contact points, as 6 c c and c7", and switch,as.E withcontact points, as e 6 a and e", and the switch arms, as e and 6 are seen in the position they occupy, as car X moves up wardly and car moves downwardly.

The, source of energy, as D, as seen in Fig. 1, has a wire 1 leading therefrom and connecting with switch arms, as e and 6 This wire 1 connects also with wires 2 and 3 which lead to and through signal devices, as G, G respectively, and back as shown, so that wire 2 connects with contact points 6 and etof automatic switch, as E, by branch wires h and it, and wire 3 connects with contact points, as e and c of switch, as E by branches h and k Only one-of the contact points, as e and 0 is in electrical connection with switch arm a at. a time, point e is in contact when car X is moving up and point 6 when such car is Also only'one of the contact points, as e andic is likewise in contact moving down.

with the arm, as 6 contact point, as 6 being in contact, as car X moves down and point, as 0 being in contact as suchcar moves up. lVhen contact point, as e, is in electrical connection with switch arm, as e of automatic switch, as E, the circuit is through wires 1, 2, h to wire 4 which leads to the yielding parts of movable portions or members, as (1 a a, &c. of the switch devices, as A, A A, &c., which, when such devices and their circuits are in operable condition, contact with conducting material, as C, as it moves over them. WVhenever this piece, as C, is in contact with any one of theyielding parts of movable members or portions, as a a, a, &c., the circuit is continued by wire 5 to the other pole of the source, asD, as shown in ,Fig. 1. When car X reverses its direction of move mentautomatic switch arm 6 moves and breaks connection with'points, as e? and c and connects with points, as e and c and then the circuit'is .from wire 2 to branch wire it contact point 6 thence by wire 8 to movable parts, as (L a, a", &c., of switch devices, as A A A", &c., for car X, thence to conducting material C, and thence by wire 5 to the other pole of the source D. Thus when car X moves upwardly, as shown in Fig. 1, the signal device G is in circuit by reason of wire 1 being in electrical con nection with arm 6 of switchE by means of branch wire k and point a and such. connection is broken through point e and wire h. When the car reverses its movement the connectionbetween point e and arm- 0 is. broken and connection is made through contact point e and such arm thereby chang' ing the flow of the current as just described.

For car X and itscariage C as shown in Fig. 1, with car moving down, the circuit is by wire 1 to wire 8 thence to and through si 'nal G back to wire 71, to contact point e,

' of swltch E to arm a, thence by wire 6 to movable yielding-parts, as a a a, &c., of

switch devlces, as A A A, &c., for car X thence to conducting material C of carriage B and by wire 7 to wire 5 and the other pole of source D. When car X changes its direction ofmovement a change-of the switch arm 6 takes place and the connection between 1t and contact points, as'e and 0, 1s broken and connection 1s made between such arm and contact points, as e and e,so that as such car moves upwardly the circuit is by wire 1 to wire 3, thence through signal device G and back to branch wire [L3, contact point e arm 6 and thence by' w-ire 9 to movable yielding parts, as a a,; a 'f &c., of switch devices, as A, A A, &c., and-thence to conducting material C and to wires 7 and 5 to the other pole of the source D. The operation for this car X is the same as for car X and as many cars and carriages with conducting materialmay be added as desired, as each car mayfbe provided with the same or duplicate circuits of those shown for either ofcars X or X seen in Fig. 1,

Of course it will be understood that each switch device and circuit which is in an inoperable condition by reason of the movable member or members thereof being in the position or positions seen in Figs. 7 and 8, as before described, there will be an air space between such member-or members and the pieces of conducting material C and C,

asthe latter move over such members, but

that with each of the movable members or portions of the several switch devices moved into the position indicated 1n Figs. 6" and 9,

the circuits will be as described above during the movement of the cars and carriagesim the full extent of movement for theseverat floors which are designed tolbe served by the particular system or apparatus.

It will be observed that wheneverthe car and its respective carriage change their direction of movement the automatic switches break ,and make connections ms described above. Also that any movable member or mcmbers that are in position for the pieces of conducting material to electrically connect with the yielding part or parts thereof in passing over the same and which are connected with contact points which at the time are out of contact with the switch arms, are incapable of operating the signal devices, and, hence, the signals will be operated only as the car moves in proper direction for the signals to be given.

The circuits forthe floor signals of car X, when moving up, as shown in Fig. 1, are as follows: from source D by' wire 1 to switch arm 6, contact point e, thence by wire 10 through signal device H and by wire 11 to movable yielding part, as a, of switch device, as A of that car and thence by piece of conducting material C and wire 5 to the other pole of source D. It will be observed that wire 10 connects with each of the signal devices H, H H, &c., at the several floors, which are operable, as car X moves upwardly, and ends with the lowermost signal device H The circuit for the next sig nal is by wirelO through signal device H and by wire 12 to .part a of switch device A thence to conducting material C and by wire 5 to the other pole of the source, It is to be understood that conducting piece of material C is at all times in electrical connection with source D by wire 5, so that any circuit reaching piece C is in connection with that pole of such source. This is also true of conducting piece of material C and wires 7 and 5, as seen in Fig. 1, and consequently, in tracing the circuits for signal devices H, H H", H &c., itwill not be necessary to trace them further than to pieces G and C The circuit for the next signal is by wire 10 through signal device H and by wire 13 to part a of switch device A and piece C. "The 'next one is by wirelO through signal device H by wire l4to part (L of device A and piece C. The remaining circuits for signal devices H, H", H and H are by wire 10 and wires 15, 16, 17 and 18, respectively, through said signal devices to yielding parts a a a and a,-re-

spectively, and thence to piece C. The circuits for the floor signals as car X moves downwardly are as follows: from switch arm 6, contact point e to wire 19, leading to all of the signal devices H ll H 810. as in the case of wire 10 and devices H, H H*, &c., and thence to the respective signal devices H H H H H", H, H and H and by Wires 20, 21,22, 23, 24, 25, 26 and 27 respectively to parts a a a a, al (4 a and a, respectively, and to conduct ing material C and source D.

The circuits forthe floor signals of car X are substantially, as seen in Fig. 1, duplicates of those for car X and the same can be readily traced without describing them in detail. Wires 30 and31 are substituted.

in the circuits for car X for wires 10 and 19 in the circuits for car X. Also wires 32, 33, 34, 35, 36, 37, 38 and 39 are substituted in the case of car X for wires 11, 12, 13, 14,

15, 16, 17 and 18, respectively, of car X, and

wires 40, 41, 42, 43, 44, 45, 46, and 47 are also substituted in the case of car X for wires 20, 21, 22, 23, 24, 25, 26 and 27, respectively, of car X, all as shown. The movable members and parts of the switch devices A, A A A, &c., are moved into positionto put the switch devices and circuits in operable condition from their normal or inoperative condition by ordinary pushbuttons or other circuit closingdevices located at the respective floors of thebuilding, there being one for each of the 'switch devices for upgoing signals and one for down going signals at each floor, as indicated diagrammatically in Fig; 5, wherein push-button N is for an upgolng signal and push-button N is for a downgoing signal. Electromagnet S 'in Fig. 5 is connected with push'button N and source D by wires 48, 49 and 50.

Push button N and source D are connected by wires 51, 52 and branch Wire y' so that magnet S can be'energized upon operating push button N. From this it will be seen that the push button portion of the means .fioor in convenient position to be operated as desired and that another, portion of such means is arranged. adjacent to the movable portion or part of the circuit which is to be moved to bring such circuit into operable condition.

If desired the retaining or holding devices may be constructed and made to'operatesomewhat diiferently from what they are shown in preceding figures, for instance, as seen in a diagrammatic way in Fig. 10, where there are no movable members or parts of the switch devices such as are shown in precedingfigures. In thisFig. 10 springs, similar to those shown in preceding figures as formi'ng one terminal of a circuit, are mounted on fixed supports and they form terminals of: .circuits as before, but they are not mounted to move mto and out of position to put the switch devices and circuits in an inoperable or operable cond ttion. This is done by aseparate switch device, as K, having an elbow lever one arm of which is provided with an armature 70 'which electromagnet O operates, when energized by push buttons 1 being-operated and the circuit through sourcel) closed. The other arm of this elbow lever is is provided with conducting material A with which one pole of source of energy D is connected by wire Conducting material 71?, when magnet O is energized, connects with spring arm 71: and makes electrical connection therewith.- This spring arm k is electrically connected with car signals G and G one for one car and the other for another car, by wire 54 and signal device G is connected with contact spring a of switch A by wire 55 and device G is connected with contact spring a of switch A by wire 56. Contact spring a 'is in electrical contact with conducting material C when the carriage, on which material C is mounted, moves over such spring and switch K is closed, and contact spring a is in electrical contact with conducting material C when. the carriage, on which such material is mounted, moves over this sprin a, and switch K is'closed. (londucting Signal device H is connected to contactspring (1 of switch A by wire 61 and device H is connected with contact spring a, of switch A", by wire 62. These con-y tact springs, as a? and a, like springs a and a are in electrical contact with pieces, as C and C, respectively, when such pieces are passing over them and switch K is closed.

As here shown there are two parts for two cars, when such cars move in one direction, as for instance, when moving in either the up or down direction. shown, if signals are to be iven when the cars are moving in both t e up and down directions, then the floor signal de vices, as G G, Contact springs, as a, a, a, a and switches E E K, would have to be duplicated in order that separate signals\be given at each floor or station in both the up and down ,directions as it takes one set of these devices working independently of all others for giving signals in the {invention shown in preceding figures of the as they are described to be operated when up direction at each floor and another similar set forgiving the signals in the 4.15-

drawings. This duplication of the above mentioned parts would, of course, require that proper connections by wires,- etc., be made with such parts and the source of energy So that the signals would be operated arranged as heretofore shown, where signals are to be given in both the up and down directions. 'This necessarily requires that theduplicated parts are to be so connected that when the car moves in the up di-' 3 rection the down signals will not be pp erated and also that when such car moves in the down direction the up signals willnot be operated. As heretofore ex plained in connection with preceding fig ures, the circuits for giving the signals when the car is moving. in the up direction,

are closed by the movement of a part of a switch, as E or E and the circuits for the giving of signals as the car moves in the down direction are opened by the move ment of a similar part of the same switch, In order that the circuits for giving signals at the different floors or stations in both directions of movement of the car in the modification shown diagrammatically in Fig. 10, the switches, as E and E must be duplicated and made operable to do the As thus able by either work done by the switches, as E and E in the embodiment disclosed in preceding portions of this specification. These switches E E referred to, shown diagrammatically have a function similar to the switches E E shown in Fig. I. The contact springs are at all times in position, in the construction seen in Fig. 10, for pieces of conducting material C and C to contact therewith, as such pieces move over, them, but the circuits with source D are broken at switch K, when that switch is open, and, therefore,the signals can only be operated when that switch is closed. This switch is closed by magnet 0, source D and push button N as before explained, wire 63 leading from magnet O to source/D wire 64 leading from said source to push button N and wire 65 leading from such push button to magnet O, as shown. As switch device K is closed a projection, as 76*, engages with the upper end ofth'e lever t, which lever forms a portion of the retaining device T When lover I? and projection is are thus engaged the switch K is held or retained in the closed condition and when either piece C or C pass over their respective contact springs the respective signals will be operated until such switch is released and the' circuit or circuits is restored to an inoperable condition. This switch K is released by means of bars, as I and I having projections, as a? and 2'", respectively, with which restoring devices, as f and f suitably mounted on con ucting pieces, as C and C respectively, engage to move such bars. Restoring device, as f, mounted on piece, as P, as indicated in Fig. 10, has not reached or has passed by projection 6 on bar I, according to the direction of its travel, and, hence, bar, as I, is in its normal position ready to be forced toward retaining device seen. Bar I is shown as having been'forced toward lever, asp-t by restoring device, as

"as f, has passed 10 projection, as 2'", bar I is free to be move toward piece C. If desired additional springs is and is, one for each bar I and bar I may be employed as indicated in Fi 10. This lever t is operar I or burl accordingly as restoring devices 7 or f engage with projections 71 or i of such bars and when once operated it remains in the position seenuntil magnet O is again energized and -T ",-so as to force lever t into the position switch K is closed, no matter, how many times restoring devices f and f may actuate bars I and I Elbow lever is is caused to move out contact with spring arm 7: by any suitable means, as for instance a spring or springs.

As shown there are two springs 70 and 1h? preferably arranged so as to act somewhat and exerts its force through only a portion of the movement of arm is, and that portion when armature A is nearest electromagnet 0. With this arrangement of springs the arm 70 may be made to move out of contact with s rin arm 77 with a. nick movement p a and the magnet O. can move its armature from a greater distance than if a single spring of suflic'ient stress to give this quick movement was used, as is well known. This 5 gives a quick break of the current, as the arm 7;: moves out of contact with spring arm Z 2 which is very desirable with a current such as is suitable for electric light purposes.

In Figs. ll, 12 and 13 a different form of restoring device is illustrated from what is shown in Figs. 1 to 9, and the retaining devices are made to engage with the blocks of insulating material on which are the contact springs or yielding parts with which the conducting pieces'mounted on the carriages contact as they pass over such springs or parts. These blocks, m m m, &c., of insulating material are mounted on movable parts or controllers a, n, 70 &c.,

which. are actuated in one direction by springs Z Z Z, &c., as the corresponding parts are operated in the construction seen in Figs. 1 to 9. These parts are also operated in the other direction by elbow levers,

{9 9 ,9 9, &c., links r r 0", &c., to which armatures si s 8 &c., are attached and electromagnets, S S S &c., which are connected with push buttons located atthe devices 0 and 0 and carriage B, which is shown as moving downwardly or in a direcscve-ral floors by circuits and which are operable as before explained, to bring the movable portions or members having yielding parts or contact springs a a, a, &o., into position to make contact with suitable .pieces of conducting material 6* and C mounted on carriages B and B and put the switch devices and their respective circuits in an operable/condition,.the same as in the construction. shown in Figs. 1 to 9, and as betoreexplained. Two of these movable members or-portions having parts. a

a, a, &c., are mounted on each of these blocks of insulating material m, m m &c-.,as in Figs. 1 to 9, and with the other parts form switch devices A, A A, &c.,

whicliarenormaliy inan inoperable condition, thatis, in a condition where there is -a clear space between the pieces of conducting material G and C, as such pieces pass over the yielding parts or contact springs,

of the movable members or portions, a, a,

(L38,.&C., of the switch devices, andno current can flow from one-to the other. As shown in these Figs. 1-1 lac-13, the restoring devices consist of pivoted plates 0 0' 0 and 0 mounted uponthe carriages B and 18 respectively, two plates for each carriage, as shown. The outermost edges of these plates which are arranged to extend beyond tlie edges or the carriages, as plates 0 and 0 are seen act upon the projections, as 2' and 5 to force such projections and retaining devices away from their respective carriages and out of engagement with their respective blocks of insulating material to release the movable members or portions of the switch devices and restore such devices and their circuits to an inoperable condition by the action oi? springs Z and into the position seen in. Fig. 12, where the parts are shown with plate or restoring device 0 in the position relatively to projection '11 of retaining device or devices T as shown in Fig. 11 and where the carriage B is moving upwardly, as indicated by an arrow. Re storing device 0 is there shown as having performed its work on retaining device T and in position to perform its Work upon any other retaining device with which it is to engage on the movement upwardly of the car and carriage B until such car and carriage reverse their direction'of movement. lVhenever this occurs these pivoted plates or restoring devices will also reverse or change positions, one with the other, so far as concerns the portions of them which extcnd'beyond the outer side edges of the carriages; that is, device 0 will move inwardly into the position, relatively to the side edge of the carriage, corresponding to that device 0 is now seen to occupy and device 0 will move outwardly into a position, corresponding to that device '0 is now seen to occupy, all as is illustrated in the case of tion opposite to that in which carriage B is shown as moving, as indicated by the arrows thereon.

When carriage B is moving up device 0 is out'of active relation to projections, as 2', on retaining devices, aslT, and device 0 is in active relation to projections,

as 2' on retainin devices as T While in j the case of carriage B device 0 is in active relation to projections, as i and device 0 is out of active relation to projections, asz'. As these carriages reverse or change their direction of movement these restoring devices change relations to their respective projections with which they co-act in the operation of the apparatus. This change in the relations of the restoring devices and their respective projections is accomplished by means of pivoted levers, as Q and Q one on each carriage. Each lever, at one end, is provided with a friction plate or device, as Q and Q respectively, and at the Opposite ends with pins or projections, as Q, and Q which work in slots Q and Q, respectively, of restoring devices, as 0, 0

and 0 as shown. These slots,- as Q and Q7, are of suitable shape and dimensions to accomplish the change in the relations of such devices relatively to the carriages and their respective retaining device projections, as just explained, when the carriages change their-direction of movement. The friction devices, as Q and Q bear upon friction bars, as Q and Q respec- 10 tively, and there is suflicient frictional contact between them, so that the levers will be moved tothe extent desired before device, as Q or Q, will slide on bar, as Q? or bar Q, respectively, suitable means being employed to secure such bars in fixed positions on frame F and also to limit the extentof moizement of these levers, as Q.

- andlQhmAsishown the ends of the slots as Q, and Q", in devices, as 0 0, 0 'andc 2 respectively, do this work of limiting the extent of the movement of such levers. If desired other constructions and arrangements of retaining or holding devices may be" employed to hold dilferently formed 25 movable members or parts of switch devices in operable condition so that a carriage or carriages may cooperate therewith and release such members and parts and restore the switch devices and their circuits to an inoperable condition, such for instance as is shownin Figs 14:, 15, 16 and 17 of the drawings. Inthe construction shown in these figures the retaining devices are actuated in one direction by springs and in 'the other by restoring devices mounted on a carriage or carriages, and in this respect these devices are essentially the same as the retaining and restoring devices in preceding figures.- Also in this construction 40 there are movable members or portions of the switch devices which are movable into and out of position where they can be oper ated by some part or portion mounted on a carriage or movable means engaging therewith and the circuits and switch devices are in an operable or inoperable condition, accordingly as such movable members or pertions are in or out of position to be operable by the carriage or carriages in passing over or relatively to them, and in this respect the construction here shown is like that shown in someof the preceding figures of the drawings. Also these movable portions or members are provided with a part or parts which yield and permit such portions or members to move into the operable position as "in the construction seen in Figs.

1 to 12. Also in this construction the restoring devices are active or inactive to re- Q lease the movable members or portions of the switch devices accordingly as the retaining or holding devices are or are not holding or retaining such members or portions in position for' their circuits to be in am operable condition as the carriage or carriages move relatively thereto, and in this respect also, this construction is substan- Instead of the switch devices being mounted to move in separate supports, as in some of the preceding figures they are, in the construction shown in Figs. 1a to 17 mounted on a bar or controller, which in turn is mounted in bearings to move back and forth to the desired extent; that is, the corresponding switch devices for a plurality of cars are thus mounted instead of each of such corresponding devices being mounted to move in its own separate support. In this respect the construction shown in Figs. 1a to 17 is different from any shown in preceding figures. Two of these bars or controllers are shown and these somewhat widely separated, but it is to be understood that two of such bars or controllers may be used for each floor to be served with signals, one for up signals and one for down signals. One of these two controllers shown is for down signals and one is for up signals, and a description of'these two will suflice for any number, as they will be substantially the same in mode of operation. These bars or controllers M and M one, M, being for the switch devices giving signals for one floor, when the cars are moving downwardly, and the other, M being for switch devices giving signals for one floor, when the same cars are moving upwardly,

attached to the frame F These controllers are actuated or moved in one direction and into the position occupied by controller M ready for the circuits to be closed, by springs, as P P respectively, and these springs normally tend to thus move these controllers from the position controller M occupies to that occupied by controller M These con trollers are moved in the opposite direction by the segments of eccentric gears n, n, a and a engaging with racks C C C and C on carriages B and B, when in position for this to be done and the carriage or carriages are moving in the proper direction. It 'Will be observed that controller M has been moved by the downward movement of rack C and its engagement with segment In into the position seen in Fig. 14, and also that rack C has passed on beyond segment 11. leaving the movable part 0 held in position to hold the movable members or portions with the springs a and a in contact and the circuit closed between them and with the signal device connected therewith in operation. These several movable ,members or portions and contact springs a, a, a, a, &c., are mounted on blocks m m, m and en, respectively, of insulating material, two springs to each block. Each of these contact springs forms one terminal of a circuit, which circuit is closed tially like that shown in preceding figures.

are mounted to slide in bars, P, P fixedly M constitute movable 'portions or memm and m being mounted on controller M Switch device A cooperates with rack .C, of carriage B device A with rack C ofcarriage-B, device A with rack C of carriage B and device A with rack C of carriage B in giving the signals or causing the signal devices to operate. As these controllers M and W are moved from the position controller M occupies to thatoccupied by controller M, by the eccentric segments a, a, n and'n engaging with their respective racks, spring pressed stops, as M and M attached to armatures M and M respectively, engage with fixed stops M9 and M, respectively, and hold such controllers from immediately returning to the positions from which they were thus moved and they are held until the spring pressed stops M and M are operated by energizing electromagnets O and 0 respectively,

and springs P and P are allowed to movesucli controllers and return them into position where their respective switch devices and their circuits will be inoperable condition until such controllers are again moved by the segmental eccentrics and the retaining devices have been operated and .the movable .parts of the switch devices are released and such devices and circuits are restored to an inoperable condition. In this construction the blocks m m, m, M33, the springs a, a a, &c.,' and the controllers M bers of the switch devices.

Each armature is provided with a spring as'Q), Fig. 15, which has to be compressed when magnet O is energized, to release stop stop M from stop 1 7 fixed to bar M This spring normally tends to press stop M? into position for it to thus engage, as shown in Fig. 18. As shown in Fig. 15 controller M is in the same position sho-vnin the upper part of Fig. 14, that is, with the stop M released from stop M and with the controller moved by the stress of its spring P into position for either segment n or segment n to engage with their respective racks on the upward movement of such racks, and whichever rack reaches its respective segment first will operate the same and move controller M from the position in which it is shown in Fig. 15 to that seen in Fig. 18,

which corresponds with the position of controller M seen in the lower part of Fig. 14. As seen in Fig. 1.4 the controller M is'in the retained position where the racks cannot contact with the segmental eccentrics and no action on the switch devices can be had until such controller and eccentrics are in the positions seen in Fig. 15, or the upper part of Fig. 14. These segmental eccentrics I are mounted o'iistuds 0 0 0 and 0 respectively, and these studs are in turn mounted or fixed in the controllers, studs 0 and 0 being fixed in controller M and studs 0 and 0' being fixed iii controller M On each of these studs there is also pivotally mounted a movable )art as 8 s s and s respectively, with which eccentrics n. n 02 and n, cooperate. One of those eccentrics as n is, seen detached from its stud in Fig. 19 and one of these movable parts, as s is seen detached from the stud in Fig. 20. As here seen the eccentric is pro vided with a stud or projection 72 with which the small end of movable. part 5 engages as such eccentric moves in a direction to move the controller, as above explained,

and the two move as one part would move,

and consequently eccentric n and movable part 8 move together and the latter is operated by the former as it is actuated by its rack cooperating therewith, but the cocentric is free to move in the other direction whenever released from the control of the rack on the carriage. This eccentric n is provided with a second pin or projection 7) with which a two armed spring Z engages, one arm with one side of the pin and the other with the other side. As a result eccentric n is free to move in either of two directions against the stress of this spring, which is seen in Figs. 16 and 17. There is a pin 22 9, Figs. 16 and 17 attached to controller h/P with which the two arms of spring Z engages to keep such arms under tension and limiting the movements of such arms in a well known manner. Movable part .9 is provided with a .pin or projection r preferably insulated'therefrom by being' in insulating material or otherwise, which, assuch part is moved by eccentric it, engages with contact spring a and moves it down into contact with contact spring a, closing the circuit and operating the signal until the two springs are moved out of contact. Corresponding springs'a anda are seen in contact in switch device A, as before explained.

Whe'n eccentric n has moved part 8 and closed spring a down against spring a these springsyield and permit pin or pro jection r to continue its movement, the contact surfaces of the springs rubbing on one another until the eccentric a has done its work of moving controllerM into position seen in Fig. 18. In this movement of the eccentric it, the parts will-be moved so thatthe outermost'upper edge of such part,

the retaining device T to,pass beyond and the action of contact springs (4 and a, as

far as portion i of retaining device T will permit and the retaining device will hold or retain such movable part 5 pin 1 and contact springs a and a in the positions'seen in Fig. 21, until such retaining device is moved against the stress of its spring r and out of engagement with part 8 when such part, by the action of the contact springs, will be moved into the position seen in Fig. 16 and the circuit will be broken quickly, as there is practically little if any resistance to the movement of part .9 on its stud 0, either before or after spring a has moved out of contact with,spring a WVhen the eccentric a fully disengages from its rack, spring Z acts and returns it to its normal position, as seen in both Figs. 16 and 21, hence, contact spring a, aided somewhat by spring aFL'd oes not have to move such eccentric, and only moves movable paris as explained.

Retaining devices T T, T and T are mounted to slide back and forth to a limited extent in suitable supportsa a, u and n fixed to the controllers M and M These retaining devices are actuated in one direction by their springs @2 0 11 and 12 respcctively, and they are actuated in the other direction by inclined surfaces 0?, 0 0 and a, so asto release the movable parts 5 8 9,8 9 and 8 respectively, and restore the switch devices and their circuits ;to an inoperable condition. Each of these retaining devices is provided with an extension or projecting portion 6 71 ,71 and 6 respectively,'with which the inclined surfaces or restoring devices 0 0, 0 and c respectively, engage to move portions t, t t-25 and t of such retaining devices out of en gagement with movable parts s, 8 8' and 8 respectively, (when engaged therewith,) and restore their respective switch devices and circuits to an inoperable condition. ;Re-

storing device, 0 in Fig. 14:, is shown as ust about ready to engage with extension or projecting part 2' aS such device is moving downward with carriage B on which it is mounted. As restoring device 0 continues its downward movement the inclined face of same comes in contact with the projection 11 and will force such projection inward and with it portion t, carrying the latter out of engagementwith movable part 8 and releasing such part from the retaining or holding action of retaining device T,and permitting such part to move into the position the corresponding part 5' is seen to occupy in Fig. i l, which corresponds to the position the part a occupies in Fig. 16.

In the construction shown in Figs. 14- to 17 each retaining device is separate from and movable independently of every other rctaining device. The movement of any one of such devices cannot release any but its own movable part and restore its own switch device and circuit to an inoperable condition. Each movable part has to be moved into positi on for its own retaining device to engage therewith and hold or retain it in operable condition and after this has occurred the re storing device adapted to engage with that particular retaining device can release it, as such restoring device moves past the retaining device. The retaining device can only engage with the movable part when such part is moved by the segmental eccentric of that switch device as such eccentric moves in proper direction to close the circuit. \Vhen such eccentric moves in the other direction, as it may moveagainst thcstress exerted by one of th arms of the two arm spring Z for instance, such movement does not move the movable part, as s for instance. This movable part is moved only when the circuit is to be closed and the switch device put into operable condition. Hence any movement of the retaining devices by the. restoring devices at other times is of no practical effect on the movable parts of the switch devices and such movements may take place without devices to an inoperable condition. For this reason the restoring devices may be fixedly attached at desired points on the carriage and there is no need of a portion being active and another portion' inactive as the carriage moves in one direction, as is the case in the constructions seen in some of the preceding figures of the drawings, and all portions of the restoring devices may be active at all times. The carriages are movable relatively to the retaining and switch devices in any well known manner, such for instance as indicated in Fig, 1, if desired, wherein rollers on studs or brackets guide and hold the carriage in proper relation to the parts with which they cooperate. Each controlleris released, so that its spring, as P, may move it into position for the eccentric or eccentrics mounted thereon to be engaged by the first approaching cooperating rack moving in a direction to actuate its respective movable part, by means of a magnet, as 0 a circuit, a source of energy and a push button. The

push button will be located at any convenientpoint from where it is desired to signal the car, as for instance, one of the floors of the building which the apparatus is to serve,

there being preferably twice as many concult connecting with a signal device, wlnch sired.

Each switch device is provided with a cirmay beope-ra ble for any given floor. This signal device is to be located in the car or elsewhere, where it is desired that the signals shall be received. Each car may have its own signal device, circuits and switch devices, and there may be as many cars as desired, or each floor may have its own signal device or devices, 620., for each car. Each controller may carry as many portions or" switch devices as there are cars to be served,

each switch device being operable independently of the others, so fares concerns the closing ofthe circuit, but each controller is movable by any one of the segmental eccentrics ofthe switch devices mounted thereon. Hence,'the first carriage that approaches a controller with the eccentrics of its switch devices in position to actuate its respective movable parts engages with its respective eccentric and moves the controller, with all of its switch devices,) 'away from all of the racks with'which such other eccentrics are to cooperate and puts all of the switch de vices on that controller in an inoperable condition until such controller is released againby operating its particular push but ton. In the construction thus shown the movable portions or members of the sw""ch devices are moved into position for the circuit or circuits connected therewith to be brought into an operable condition by the actionrof springs and such portions or members are moved into such positions to substantially the same extent when the segmental eccentrics are opposite their respective cooperating racks as when such racks are in hence, the movement of such portions or the switch devices is not interfered with by the movements of their coact'ing racks past the segments of eccentric gears mounted on the controllers. These controllers form means which connect two or'more movable portions or members of the switch devices together and by which such portions or meme here may be moved simultaneously and the circuits bebrought into andout of an operable condition.

' Signal device Gr, diagrammatically indicated near the upper right hand corner of Fig. 14 isconnected with switch devices coacting with carriage B, and signal device G vis connected with switch devices coactin;

with carriage r. ,as' is indicated in similar devices 1. on one manner at the upper left hand corner of Fig. 14. The push buttons N and N magnets O 'and and source of energy D are also in like manner indicated at the lower left hand corner of this Fig. 14:: Source of energy D for signal devices G and G is diagrammatically indicated just above the central portion of Fig. 1a. Push button N is connected to magnet O and source D by wires 66, 67 and 68 and push button N is connectedto magnet O and source D' by wires 69, 67, 70 and 71. The signal device G is connected with switch devices A, A, and'source D by suitable wires. lVire 72 leads from source D to signal device G from which wire 73 leads to contact spring a, which contacts with spring a having wire 7% leading to wire 75 which connects with the other side of. source 1). Tire 73 also connects with wire 76 which connects a contact spring a which contacts with spring a which in turn connects with wires 7st and 75 and the other side of source D Signal device G is connected with switch lows: ire Z 7 leads from such source to such sinal, .rrom the-signal a wire 78 leads to contact spring (0 and from contact spring a of this same switch device A a wire 75 leads back to source D; from wire 78 a wire 79 leads to'contact spring a, and from contact spring a of this switch device A a wire 80 leads to wire 75 and thence to source D In this construction each circuit may be said to begin one contact spring of each switch device and end with the companion contact spring of such device, passing through the and A and source D as folsignal device for that switch device on its way, that is, each circuit may be complete at all times, except at the switch device,

where it is closed by the movement of the" movabl 'part mounted on its stud. By rea s'each circuit is practically inde other circuit, and there is little or no danger oi cross circuiting in the apparatus. Also the cont-act'springs have a rubbingcontact another and cause a. quick break in the circuit when they separate upon being released from the-control of the movable through the action of the retaining devices. The features in this construction shown in Figs. 14; to 17 not, in general, common with the constructions shown in precedfigures are not claimed herein, but form the subject matter of another application Serial No. 234,358, filed November 26, 1904.

The retaining devices may beconstructed in various forms and yet be adapted to serve sam purposes in the same way in the combinations or devices herein described. Also d rent forms of restoring means may er-vi i yeti to e'fife t the restoration of the switch devices and connected circuits to an inoperable condition. Also the construction of the individual switch devices may vary widely and yet such devices will be adapted to do the work done by any of the switch devices shown in the preceding figures of the drawings in the combinations of devices herein pointed out and each will do this work in the same way and without changing the mode of operation of the combinations or the manner of combining the devices together. For instance, the switch devices, instead of being constructed as shown in preceding figures, may be constructed as shown in Figs. 22 and 23 where each switch device consists of a movable part or controller carrying two terminals of a circuit mounted in a support fixed in position inthe apparatus. This movable part, as shown in Fig. 23, is spring actuated in one direction by spring Z and is actuated in the opposite direction by an elbow lever ,link 'r armature 8 and electromagnet S, Fig. 22, which magnet is energir cd by any desired form of push button device and source of energy, in a manner similar to that shown in preceding figures of the drawings. Also instead of the retaining devices for two or more switch devices being made from one piece of material, so that such retaining devices move simultaneously they may be made out of separate pieces of material and connected together in any desired manner, for instance as seen in Figs.

22 and 24, and to connect with the switch devices and be actuated by the restoring means, carried on the carriage, as there shown. The switch devices A and A, as shown, are each provided with two terminals as a a a and a These terminals of each switch device are made to contact, one with the other, by the engagement of the respective carriage therewith, as such carriage.

moves over and in engagement therewith, by pressing the terminal, as a into contact with terminal a and holding the two in contact, as seen in Fig. 24, until such car'- riage' has passed on and the restoring devices, as 0 and 0, carried by the carriage, have actuated the retaining device for that particular switch device, when, such terminals are moved from the osition seen in Fig. 2a to that which they occupy in Fig. 22, or are moved from an operative condition, as seen in Fig. 24, to an inoperative condition as seen in Fig.22. The controller a, block m and contact springs or. terminals a and a form a movable portion or member ofthe switch device A. These contactsprings or terminals (1 and (1 can yield when the carriage is in position over them and by reason of-this the movable portion or member of the switch device ispermitted to move to substantially the same extent when the carriage is in this position as when in other positions relatively to the switch device. These retaining devices, as Ti and operable condition.

T seen in Figs. 22 to 24 are pivotally mounted on their respective switch devices A and A and each is provided with an.

engaging part, as 25 and t, respectively, which engage with a pro ect1ng part or pm of the controller a, as shown, and prevents such controller from moving under the stress of the spring Z until such retammg device I or devices are moved by a restoring device carried by one of the carriagesB or B These retaining devices T and T are connected together, so as to move simultaneously, by a link L, which is spring actuated in one direction by a spring L. This spring tends to hold the retaining devices in position to engage with the controllers n and a whenever such controllers are moved into position where this engagement can take place.

In Fig. 22 the restoring device 0 is shown in engagment with the projecting portion 11* of retaining device T and has partially actuated the retaining device T from the position seen in Fig. 24, to that seen in Fig. 22, as such restoring device is moving past such retaining device. storing device 0 is shown in the position it occupies when the carriage 13 is moving in the opposite direction tothat in which it is assumed to be moving in Fig. 22, and illustrates how such device may move past such retaining device without actuating the same, when such retaining device or devices are set to be actuated by a carriage moving in a direction opposite to that in which it or they are to be actuated, as hereinbefore explained in connection with Figs. 11 to 13, where the same kind of restoring devices are shown. The restoring devices are operated in the construction illustrated'in Figs. 22

to 24: by meanssimilar to what is shown in Figs. 11 to 13 and the description given in connection with these Figs. 11 to 13 will suffice, it is believed, for the construction shown in Figs. 22 to 24, there being a pivoted lever as Q, with a frictional connection between it and a bar, as Q, and a pin and slot connection at the other end thereof with the restoring devices 0 and a, mounted on carriage'B which in turn is'mounted to move in guides secured to the frame F of the apparatus all as fully shown in Figs. 11 to 13. In this construction, as in preceding ones, there are circuits and switch devices normally in an inoperable condition, means adapted to bring such circuits and devices into operable condition, retaining means adapted to retain or hold such devices in such condition and restoring means adapted to restore such circuits and devices to an in- I'have herein shown and described different embodiments of my invention wherein In Fig. 24 this redevices, retaining or holding means and re- In other applications of mine such as 234,357 and 234,358 modifications not herein specifically claimed, are more specifically claimed.
